' 4 Claims. (Cl 101-293) My invention relates to that class of pressesfor printing wax carbon. spots on sheets of My invention has for itsobject to provide a construction whereby the ordinary job press.

having a revolving disk such as the well known Chandler and Price press,which is standard construction, may be changed so that it is possible toproduce wax carbon spots located in any predetermined position on thepaper in as great a variety as is desired. As will be seen from thehereinafter contained description my invention can be applied to a pressof this type without destroying its usefulness for ordinary printinswork.

My invention has for its further object to provide electrical means toheat the revolving disk.

A further object to provide means to insure the positive rotation of theform rollers.

A further object to provide for the continuous rotation of the vibratorroller.

A further object to provide means whereby the inking rollers may beheated notwithstanding their movement. I

Other objects and novel means will be seen .from the hereinaftercontained description.

My means of accomplishing the foregoing objects may be more, readilyunderstood by havlng reference to the accompanying drawings which arehereunto annexed and are a part of this specification, in which- Fig. 1is a perspective view of one side of the press;

As shown in the drawings, my improvement is shown as stated, on the wellknown Chandler and Price press, the details of which are so wellunderstood in the trade that I shall not describe them but shall confinemy description to such parts as I have added to adapt the press toproduce wax carbon spots on sheets of paper.

It is well known that in order to successfully print spots of wax carbonon sheets of paper it is not only necessary to melt the wax carbon inthe ink fountain and to maintain it at a predetermined temperature, butall of the parts of the press which come in contact with the wax carbonmust also be maintained at the correct temperature.

It has been found in practice that if this temperature varies either upor down beyond a certain predetermined degree the press will beinoperative in so far as producing wax carbon spots which will transferproperly.

In order to accomplish this result, I provide.

an electric heater I for the ink fountain bed 2 which contains themelted wax carbon.

temperature. As is well understood this roller t I 2 fastened to oneside of the press. The brushes l0 and II are connected by means ofelectrical conductors i3 and I4 by a suitable source of electric currentsupply (not shown). These conductor roller l by means of an intermediaterubber roller l5 which rides the ink fountain roller 4 continually. Thisroller I6 is driven by means of a gear mounted on the end of its shaft.This gear I! meshes with a gear l8 mounted on the shaft of the fountainroller 4. Friction gears may, if desired, be substituted for the spurgears illustrated.

The melted carbon is delivered to the ductor roller by means of anintermediate roller IS. The steel ductor roller l5 swings back and forthbetween the roller l6 shown as in Fig. 2 and the position indicated inthe dotted lines in the same figure. While in the position shown indotted lines in Fig. 2, the ductor roller I5 is brought in contact withthe upper one of the two form rollers l9 and 20 which at this time isnearing its extreme upward stroke.

The rubber form roller l9 takes its supply of melted carbon from theductor roller l5 and on its downward stroke deposits this carbon on therevolving inking disk 2| where the carbon is evenly distributed by theintermittent revolutions of the inking disk 2|. As is understood bypersons skilled in the art the movement of the inking plates 2| isbrought about by beveled gears (not shown) in the well understoodmanner.

In order to further facilitate the distribution and to insure that thecarbon transferred is kept in a melted condition and at the propertemperature at all times, the rubber form rollers l3 and 20 are heatedby a steel vibrator 22 which contains an electric heating element 30mounted inside of the vibrator 22 which gets its supply of current bythe means of slip rings 24 and 25 carried on the end 26 of the vibratorshaft.

These. slip rings are arranged to contact with brushes 21 which receivetheir supply of electric current through conductors 28 and 29 which areflexible swinging lines and lead to a source of electric current supply(not shown).

It has been found that there is not sufflcient tack in the melted waxcarbon to insure the rotation of the steel vibrator 22 solely byfrictional contact with the rubber rollers l9 and 20. Therefore, inorder to-make this rotation positive, I place a gear 3| on the end ofthe shaft of the roller 20 and a similar gear 32 on the shaft of theroller l9. These gears 3| and 32 mesh with a spur gear 33 put on the endof the shaft of the vibrator 22. It will be apparent from this that itis impossible for the rollers l3 and 20 to revolve without bringingabout a revolution of the vibrator 22.

However, these rollers l9 and 20 are designed to be rotated by means ofroller trucks 34 and 35 placed adjacent the ends of the roller is andcorresponding roller trucks 36 and 31 placed adjacent the ends of theroller 20. This does not necessarily insure positive rotation and thereis considerable danger of there being a slippage of the trucks which,while not greatly objectionthe roller trucks 34, 35, 36 and 31 with theresult that I am able to obtain a positive turning of the rubber rollersl3 and 20.

Practice has shown that unless the ink plate is heated the moment thatthe carbon is delivered to it from the form roller I3, it willcrystallize. I avoid this by providing a construction which permits meto maintain the revolving disk ink plate at any predeterminedtemperature. I accomplish this in the manner clearly shown in Figs. 11to 14 inclusive and in the wiring diagram; as shown in these views Iprovide two 1 rings 42 and 43 which are preferably formed of brass orother suitable conducting material. These rings are mounted upon anannular strip of insulator 44 which is secured to the back of therevolving disk ink plate 2|. These rings 42 and 43 are connected toannular electrical heating elements 45 and 46 by means of electricalconductors 41 and 48 in the conventional manner. Current is conveyed tothe rings 42 and 43 by means. of brushes 49 and 50 of standardconstruction. These brushes are mounted in a support 5| which may bebolted or otherwise secured to the side frame 38 of the press. Thebrushes are connected to electrical conductors 52 and 53 which lead to asource of electric current supply (not shown).

The result of this construction is obvious. The rotation of therevolving disk plate 2| has no effect whatever on the electricalconnections. It is thus possible to convey the requisite amount ofcurrent to the heating elements 45 and 46 to maintain the revolving diskat any required temperature.

It is also essential that the type bed be heated to a predeterminedtemperature or it will have the effect of crystallizing the wax carbonwhen it is sought to deliver it from the rollers l3 and 20. My means ofaccomplishing this is clearly seen in Figs. 8 to 10 inclusive and in thewiring diagram. I attain this result by mounting a plurality of heatingelements 54 in the type bed 55 and I also mount a theme couple 56between the elements 54. This thermo couple is connected to pyrometerlead wires 51 and 58 which lead to a pyrometer of standard construction(not shown) for controlling the current supply (not shown).

It will be obvious from the foregoing description, that as long as theheat is turned off, the press can be used for standard purposes and whenit is desired to run a job of wax spot carboning all that is necessaryto do is to turn on the current, place the requisite amount of waxcarbon compound in the ink fountain which will be quickly melted bymeans of an electric heating element I mounted in the front of the inkfountain 2. The element being connected by means of electric conductors6| and 62 to the source of current supply, a theme couple 53 is mountedadjacent the heating element and is connected by means of lead wires 65and "'to the pyrometer and as long as the current is kept turned on allof the necessary parts of the press will be maintained at the correcttemperature for spot carboning.

Although I have described a specific form of construction foraccomplishing the desired objects, it will be obvious to persons skilledin the art that changes may be made without departing from the spirit ofmy invention and I do not desire to limit except as such limitations mayappear in the hereinafter contained claims.

Having described-my invention what I regard taut with said bed and disk,of a heated ink as new and desire to secure by Letters Patent 1.
